MOSCOW (Sputnik) – Jammeh, who ruled the country for 22 years, surprisingly lost the latest election, gaining 36.7% of votes against Barrow's 45.5%.
"After a thorough investigation, I have decided to reject the outcome of the recent election. I lament serious and unacceptable abnormalities which have reportedly transpired during the electoral process," Jammeh said on Friday, as quoted by The Guardian.
He added that he was calling for new elections that would be transparent.
Last week, the White House praised Gambia’s presidential election as "peaceful and democratic."
The chair of Gambia’s new ruling coalition has announced that Jammeh would be prosecuted for the alleged crimes he committed during his rule.
Barrow is supposed to assume presidency in Gambia in January.
